FMEA (Failure Mode and Effects Analysis) is a systematic method to characterize product and process problems. As a standard document, an FMEA is produced during the design of a product or system. However, once a system is deployed, the corresponding FMEA is rarely validated and updated. This is mainly due to the lack of method to validate and update FMEA. This paper argues that historical maint...
power transformers are important equipments in power systems. thus there is a large number of researches devoted of power transformers. however, there is still a demand for future investigations, especially in the field of diagnosis of transformer failures. in order to fulfill the demand, the first part reports a study case in which four main types of failures on the active part are investigate...
background: the reliability and safety of gas refineries are strongly associated with the reliability of other parts of the system. defect and failure in one part of a system can cause total system breakdown or accident. the failure and damage in these equipment such as transformers and boilers results in not only the equipment damage and human injuries but also productivity reduction. the purp...
Increasingly complex systems lead to an interweaving of security, safety, availability and reliability concerns. Most dependability analysis techniques do not include security aspects. In order to include security, a holistic risk model for systems is needed. In our novel approach, the basic failure cause, failure mode and failure effect model known from FMEA is used as a template for a vulnera...
FMEA(Failure Mode and Effects Analysis) is a systematic method of identifying and preventing system, product and process problems. As a standard document, FMEA is produced during the design of products or systems. However, FMEA documentation is rarely validated or updated in practice after it was generated. FMEA validation remains a challenge. In this technical report, we propose to validate FM...
The failure mode and effects analysis (FMEA) is a widely used analytical technique that helps to identify and reduce the risks of failure in a system, component, or process. One important issue of FMEA is the determination of the risk priorities of failure modes. Risk ranking is produced in order to prioritize the focus on each of the failure modes that are identified. In this study, we applied...
از نخستین و مهمترین چالشهای رودروی انجام پروژه های انتخاب مناسب ترین روش اجرای پروژه می باشد. برای اجرای پروژه روشهای گوناگونی وجود دارد که اجرای پروژه به روش epc (engineering , procurement, construction) در بعضی موار راهکاری مناسب به نظر می رسد. شناخت کامل اهداف و عوامل مختلف پروژه از جمله عدم قطعیت ها و ریسک های موجود، تعامل این اهداف با روش اجرای پروژه و نهایتا مدیریت انها امری ضروری می باشد...
In any organization, the importance of failuremanagement cannot bementionedby a single word. However,most failure analysis is dominated by themanufacturing sector, despite the increasing importance of the service sector. In response, this paper proposes a systematic approach for identifying and evaluating potential failures using a service-specific failure mode and effect analysis (service-spec...

prevention of medication errors in neonatal intensive care units (nicus) is of paramount importance due to age-specific and physiological conditions of neonates. this study aimed to evaluate the risk of medication prescription and administration via failure mode and effects analysis (fmea), which was carried out at the research and medical teaching center of imam reza hospital in mashhad, iran....
